Abstract
A hydraulic excavator includes an engine, a rotating frame, a vehicle body frame, a diesel particulate filtering device, a selective catalytic reduction device, and a connecting pipe. The diesel particulate filtering device and the selective catalytic reduction device are supported by a vehicle body frame. At least a portion of the connecting pipe includes an extendable bellows part. The connecting pipe connects the engine and the diesel particulate filtering device. The diesel particulate filtering device is located further away from the engine than the selective catalytic reduction device along a first direction on a horizontal plane. The first tubular body portion of the diesel particulate filtering device and the second tubular body portion of the selective catalytic reduction device are disposed apart from each other with a space therebetween in a plan view.
